The Artemis II Mission involved a ten-day test flight that carried NASA’s Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency (CSA) astronaut Jeremy Hansen 252,756 miles from Earth before splashing down off the coast of San Diego. This mission tested Orion’s life-support, navigation, and deep-space systems and set the stage for future U.S.-crewed lunar landings and, eventually, the first missions to Mars.
